Title: Detecting method of flash state of fluid
IPC: G01N21/59
Filed: 1992-03-19
Abstract: PURPOSE:To obtain a flash state detecting method whereby it is easily and positively detected at low cost whether a fluid running in a piping is in the flash state or in the liquid phase or gas phase, and which is readily applicable to a safety system in a freezing circuit or the like. CONSTITUTION:According to this method for detecting the flash state of a fluid, a light emitting part 2 is arranged so that an optical axis L is inclined with angles other than right angles to a moving direction X of a fluid running in a piping 1.

Filed: 1994-03-31
Abstract: PURPOSE:To provide a process for the preparation of cod roe seasoned with MISO (fermented bean paste), meeting the recent tendency to prefer natural foods and using cod roe as a raw material by using MISO in place of salt to suppress the salt concentration and impart the color and taste of MISO without using additives such as color-developing agent and colorant. CONSTITUTION:This process for seasoning cod roe with MISO comprises the washing of raw cod roe and the immersion of the roe in 0.5-2 times weight of MISO bed to effect the dehydration of cod roe with the MISO and the application of prescribed texture, color, taste and flavor to the cod roe. As an alternative, raw cod roe is steamed to effect the coagulation of the protein and the steamed roe is immersed in a MISO bed having low salt content to impart the roe with unique texture and low salt concentration. The cod roe pickled with MISO is smoked to impart unique taste, flavor and texture and improve the preservability. A cod roe boiled in MISO and having the taste and flavor of MISO and low salt content can be prepared by washing raw cod roe and heating in a seasoning MISO liquid, thereby imparting the cod roe with the color, taste and flavor of MISO.

Abstract: PROBLEM TO BE SOLVED: To collect and house shavings simply and positively by attracting eraser crumbs as a magnet is approached to a shaving attracting plate, and causing the attracted crumbs to fall off as the magnet is moved away therefrom in an india rubber with a ferromagnetic body blended therein. SOLUTION: When set in approximately parallel with the paper surface for attracting crumbs on the paper surface by the attracting plate 3 of an attracting device, the magnet 5 suspended by a shaft 7 or the like falls onto the rear side surface of the attracting plate 3 so that it comes to be in a cross contact state with the rear side surface of the attracting plate 3. Thus, the magnetism exerts through the attracting plate 3 of plastics or the like so as to attract crumbs on the paper surface on the surface of the attracting plate 3. When the attracting device is set up, the magnet 5 is moved apart from the attracting plate 3 to then be in cross contact with a magnet housing plate 8. A yoke 6 assists in far shooting lines of magnetic force, at the same time, in attenuating the effect of magnetic force to the attracting plate 3.  Accordingly, the crumbs attracted on the attracting plate 3 falls off the attracting plate 3, and then housed in a housing case via a baffle plate 9.

Abstract: PURPOSE:To provide a fin which is highly resistant against clogging with frost by a method wherein a slit having a flat top part is arranged at a height which is approximately coincided with a downstream fin where it is an air upstream side from a front edge of a short fin at an extremity end of a long fin. CONSTITUTION:Hot flowing air having a plenty of water vapor is cooled a little at an extremity end of a long fin 1a, changed into a condensed water or frost and leaves water vapor. Air flowing into an intermeditate part between long fins la is cooled a little by extremity end slits 3, changed into condensed water or frost and leaves water vapor. Then, the air is reached to the extremity end of the short fins 1b. The extremity ends of the short fins 1b have a little lower temperature than that of the extremity ends of the long fins 1a or the extremity end slits 3. So, in this area, some of the water vapor contained in the air are changed into frost and left on the surfaces of the fins. However, the water vapor is reduced a little, so that an amount of frost adhered to the extremity ends of the short fins 1b is reduced as compared with the case that the extremity end slits 3 are not present.
